COTTON TYPE SPINNING

Cotton type spinning is not only one specific spinning technique. Ring spinning, open end spinning or air jet spinning are comprised in this notion. But what are the differences between them? And what consitutes cotton type spinning? 

WHAT IS COTTON TYPE SPINNING?

Cotton type spinning includes the following techniques:
 

Originally used only with cotton, it is nowadays possible to spin other materials by cotton type spinning as well. A limitation what kind of materials hardly exist.


Important with cotton type spinning is for the fibers to be in a cutlength between 35-40mm, whereas the most popular cutlength is 38mm. In case a fiber is longer, other spinning techniques should be applied. It is also possible to "cottonize" fibers that are longer, meaning to cut them shorter. 
If fibers are critically shorter than 35mm, they are in general not destined for cotton type spinning or any other spinning application. 
 

MATERIALS FOR COTTON TYPE SPINNING

There are no restrictions as to what materials can be used with the cotton type spinning. Important is simply the required cutlength of 30-40mm as mentionned above. It is therefore possible to spin fibers of the following exemplary materials by cotton type spinning as well:

 

Swicofil is able to source all these mentionned fibers and many more for your cotton type spinning application. Please contact us and let us know all your requirements as per inquiry checklist.
 

COTTON TYPE SPINNING PROCESS

The cotton type spinning process generally employs seven steps, four basic steps as mentionned here and three additional:

 
  1. Opening & loosing
    Upon arrival at the mill, the fiber bails are opened and loosened. This helps separate and clean the fibers before they are fed into carding machines.
     
  2. Carding
    Carding machines further loosen and separate the fibers by passing them between two rotating metal drums covered with wire needles. This aligns the fibers in a thin web of parallel fibers which are formed into a ropelike strand called a sliver. The sliver is collected in a sliver can in preparation for roving.
     
  3. Combing
    For high quality yarns, the sliver is combed after carding to make fibers more parallel and remove smaller fibers.
     
  4. Drawing
    Skuver are then drawn out, blending the fibers and making them more parallel. No twist is added to the sliver during drawing. Several slivers can be blended together during drawing. Slivers can go through multiple drawings for further parallelization and blending.
     
  5. Roving
    Drawn slivers are then fed to the roving frame where they fibers are drawn further whilst a slight twist is added. The roving strands are collected in cans and fed to the spinning machine.
     
  6. Spinning
    The spinning machine draws out the roving strands, adds twist and winds the yarn onto bobbins.
     
  7. Winding
    Multiple bobbins pf yarn are then wound onto larger spools called cheeses. Now the yarn is ready for texturing and dyeing - and finally for weaving into fabric.
